Fun Facts About Scuba Diving

Updated: Apr 6, 2020

These are things you may not know about Scuba Diving, or even if you know already just read it again for fun.

1. “DROWNING” Most people are afraid of being drowned, but in fact, drowning is a lot harder than you can imagine. Actually, the human body has lighter mass than saltwater, saltwater is denser, and hence you will float more. So, if you going to be drowned you have to work so hard about it. That’s why we have to use the weigh system in Scuba Diving to help you descend. Because most people float, which is good if you like to stay at the surface to do “Scuba-Snorkeling” for the whole dive.

2. “WETSUIT” "Wetsuit" is a special suit worn by Scuba Divers. It is made from rubber materials called Neoprene. The thin layers of water between diver’s skin and Neoprene keeps the diver warm and retain body heat. Wetsuit does not only help the divers avoid hypothermia, a dangerously low body temperature, it also protects your skin and your body against minor harm from some marine animals and rocky reefs. Moreover, the good wetsuit has to keep your body in shape so it can make you look good in the photographs.

3. “SCUBA MASK” Diving without a scuba mask could be a little bit more than blind in exploring the underwater world. It is the most important personal piece of kit that you will need for the whole dive. You will see the amazing reefs, wrecks and other marine lives though the tempered glass lenses. The good scuba mask requires good vision and comfort. You have to be able to easily pinch your nose while you equalize and easily clear water without a lot of effort.

Scuba Mask Tips: wear the mask to cover your nose as well, do not cover only your eyes. It would not help any.

4. “STRANGE SOUNDS UNDERWATER” Wonder why everything sounds so strange as soon as you get down underwater? It works like this. When you are on the land, sound travel in waves through the air until they reach your ears and vibrate your bones in the inner ears. But underwater, soundwaves do not travel through the air, they go straight to your ears through the water. Soundwaves move 5 times faster in the water than in the air. On average, 65% of your body is H2O so yes, your body is made out of water. Because of that, you can’t figure out where the sounds coming from, the direction, or how far it is and sometimes you can’t hear the lower ones but higher frequencies.

5. “WATER ENTRY METHOD” The five most common scuba diving entry techniques can be; “Giant Stride” - It is probably the most common way to enter for deep water.

“Forward Roll” – best used on large bottom boats.

“Back Roll” – which is best used on smaller dive boats.

“Seated Entry” – very useful for shallow water or to enter quietly.

“Shore Entry wading” – walking from the shore, with or without fins

There are so many techniques and many more details about entering the water but there is no best method defined. It is usually determined by a combination of the type of platform you are diving from, what you’re most comfortable using, and the safest way determined by the conditions. There is one more way we would not recommend you to do, “Being Kicked Down” – can be done by your buddy or anyone else on the boat. This method can be harmful, also no deep or shallow water recommended. Do not do this to your friends or anyone.

6. “PRESS THE BCD BUTTON” “BCD” stands for Buoyancy Control Devices. We use BCD to control our buoyancy both on the surface and underwater. There is Air Bladder in a BCD that inflated with air from your cylinder. As you ascend, you release air to prevent air in your BCD from causing an uncontrolled or rapid ascent and vice versa, as you descend, you add air to the BCD. When you want to come up floating, you need to press the inflator button. It is always the closest button to the air inlet. Pressing the inflator button adds air to the BCD. Pushing the button expecting you will go up is a lot different from the button that will send you to space. It can bring you up only on the surface, could not bring you any higher than that.


7. “ALIEN BLOOD” If you see your buddy bleeding green blood underwater, he or she is definitely not alien. Here is the reason why. In fact, blood does not change color from red to emerald green at all. What changes down there is the light in the water. Different colors below 15 meters get absorbed by water at different rates. Red color disappears quicker but blue and green colors travel longer than red underwater.

8. “THE FINS” Do you know that most fins have no left or right? They are identical. Both sides are the same. It doesn’t matter which fin goes on which foot. In this case, you will always find the fins foot pocket and fin design and blade the exact same for each pair of the fin. So it is less customized for each foot. Do not waste your time figuring out if you are wearing the fins correctly to your left foot or right foot.
